Will having sex affect athletic performance? It might make you tired, but probably not
There is a lack of research on the topic, scientists say
Ever since the ancient Olympic Games commenced about 776 B.C., tales of athletes secretly engaging in sex at the ceremonies have become common knowledge. As former Olympic swimmer Dara Torres told CNN in 2012, “What happens in the [Olympic] Village stays in the Village.”
Now, with the 2016 Summer Olympics underway in Rio de Janeiro, the idea of athletes “getting busy” is back in the spotlight. About 450,000 condoms were allocated this year for athletes to have safe sex.

For those who decide to partake in sexual activity, will doing the deed dampen athletic performance on the court, track or field or in the ring?
What athletes say about sex
The idea dates to ancient Greece and traditional Chinese medicine, which both suggest that abstaining from sex could increase frustration and aggression, and boost energy, said David Bishop, research leader at Victoria University’s Institute of Sport, Exercise and Active Living in Melbourne, Australia.
Remember the 1976 film “Rocky”? In the movie, boxer Rocky Balboa’s trainer, Mickey, declares that “women weaken legs,” suggesting that the athlete should put romance on hold while training and competing.
Along those same lines, Mexico’s soccer team announced in 2014 that its players were asked to abstain from sex during the World Cup in Brazil in order to maximize their athletic performance. The team lost in the round of 16, as they had in every World Cup since 1994.
On the other hand, MMA fighter Ronda Rousey – holder of a 12-1 UFC record – told Showtime’s Jim Rome in 2012 that she tries to have “as much sex as possible” before a fight since it has been linked to higher testosterone levels in women.
Nonetheless, very few studies have scientifically examined how sex can improve or impair athletic performance – if at all, Bishop said. He added that he is only aware of four, and “all of the studies have been on males.”
A lack of research
The research that Bishop cited includes a small study published in the Journal of Sports Medicine and Physical Fitness in 2000, which involved 15 high-level athletes between the ages of 20 and 40 who participated in a two-day experiment.
The athletes were instructed to abstain from sex for at least 24 hours before the beginning of the study. On the first day, they completed a stress test on an exercise bike in the morning, a mental test designed to measure concentration in the afternoon and then a second stress test on an exercise bike later in the afternoon.
In between the mental test and the second stress test, about 4:15 p.m., blood samples were taken for testosterone measurements.
Next, the athletes had sexual relations with their usual partners, who were aware of the protocol of the research. The following day, the athletes participated in the same tests and had their testosterone levels measured again.
The researchers found that sexual activity had no significant overall effect on how the athletes performed during the exercise and mental tests. However, during the morning exercise test after sex, the researchers noticed slightly higher heart-rate levels.
They concluded that “the recovery capacity of an athlete could be affected if he had sexual intercourse approximately 2 hours before a competition event.”
A separate paper, published last month in the journal Frontiers in Physiology, found that sex had no significant effect on athletic performance. The paper involved a systematic review of nine studies on the topic of sexual activity and athleticism.
Those researchers concluded that “The present review demonstrates that sex activity in sport is poorly investigated in both males and females. However, the data available do not really support the misconception that sex activity can produce a negative effect on the athlete’s performance.”
Sex advice for athletes
All in all, athletes attending the Olympic Games in Rio this month should not worry excessively about how sex may affect their competitions, said Emmanuele Jannini, professor of endocrinology and medical sexology at the University of Rome-Tor Vergata in Italy.
“Sex is not just fun but also healthy,” he said, “however, if concentration is important, I would suggest to avoid sex for some few days before the game.”
Bishop, the sports scientist in Australia, advised against having sex only if it was going to affect sleep.
“If sex is going to affect performance, it will be via a lack of sleep. … Wait until after your final event,” he said, adding, “but I can’t see any problems with having sex and then getting a good night’s sleep.”
However, the current consensus among coaches and trainers seems to be that each athlete should make the individual choice of whether to have sex in the midst of a major competition.

“Current thinking in elite sports is that athletes should act in ways they consider ‘normal’ and not do something that goes against their beliefs, which will induce guilt, such as believing pre-competition sex is not good for you and yet engage in sex anyway,” said Mark Anshel, professor emeritus at Middle Tennessee State University’s Department of Health and Human Performance.
“A lot of athletes feel guilt-free and OK about pre-competition sex because it helps them sleep better as long as their sleep is not disrupted and sex does not follow a night of partying and alcohol intake,” he said. “Most contemporary coaches seem to agree.”
